Temperature roller coaster ahead for the Midwest, Northeast
Warm air surging north will clash with cold air and bring the risk of severe thunderstorms, rain and even some snow to the Midwest and Northeast ahead of an early-week cooldown.
A snowdrift turned into a tunnellike “portal” in downtown Toronto after a storm as windblown snow piled high enough for one kid to play inside.
A clash of warm and cold air set the stage for an active end to the weekend for the Ohio Valley and Northeast. Warmth surged across the area Sunday before potent thunderstorms brought hail, damaging wind gusts and flooding downpours.
Closer to the coast in locations like New York City and Atlantic City, New Jersey, temperatures weren't as high but still reached into the 60s, which is around 10-15 degrees above historical averages for the end of March.
As the storm moves off to the east, cold air is rapidly surging into portions of the Ohio Valley and the Northeast, sending locations on a temperature roller coaster.
Temperatures will drop as rain continues across parts of the Northeast Monday morning. Any standing water can produce icy spots, particularly on bridges and overpasses, when temperatures fall below freezing Monday morning.

Farther north, where colder air is already in place, precipitation can fall as snow, or even a wintry mix. Heavier snow showers later Monday afternoon and evening across New England can cause rapid reductions in visibility and slippery travel.
As much colder air spills southward, those in the Northeast won't be the only ones with much colder weather, as colder air will also extend into portions of the Midwest and Plains on Monday. Temperatures will be 20-30 degrees lower in some areas of the Ohio Valley and the mid-Atlantic. For example, after a high in the mid-70s on Sunday in Pittsburgh, temperatures are only expected to top out in the lower 40s on Monday.
Those hoping for warmth won't have to wait long as warm air is once again expected to surge northward into the Midwest and Northeast towards the later parts of the week. Thursday, highs can rise back into the 60s and 70s for many. Like the previous surge of warmth, it will not last long as another storm and associated front will move through Thursday into Friday, knocking temperatures back down on Friday into the start of the weekend in its wake.
